  // so I was experimenting with my code and it crashed before I could save it, which meant I lost the link to the reference that helped me figure out that floor is needed in order to randomly generate a number for colors, which is an array.

  // this is a similar code but not the one I used: https://editor.p5js.org/LizPina/sketches/9LF5GRL7

  }

  // for(myCurve of BezierCurves) {

  //   myCurve.show();
